Benzene thiab benzyl cawv feem ntau tsis meej pem vim lawv cov npe zoo sib xws, tab sis lawv yog ob yam tshuaj sib txawv nrog cov qauv sib txawv, cov khoom, thiab kev siv.
benzyl cawv (BA) yog dab tsi?
Benzyl cawvyog ib hom kua uas tsis muaj xim pob tshab; Nws xa tawm me ntsis tshuaj tsw qab, vim tias nws cov ntxhiab tsw thiab tsw ntawm iab almond yog muab tso rau ntev thiab oxidized rau benzaldehyde thiab benzyl acid.
Kev siv Benzyl cawv
Benzyl cawv feem ntau yog siv los ua cov kuab tshuaj thiab tshuaj tua kab mob, tab sis nws kuj tau pom siv los ua tshuaj tua kab mob thiab tshuaj loog hauv zos. Nws kuj yog siv los ua raw khoom rau ntau yam esters, siv hauv xab npum, naj hoom, thiab tsw industries.
benzene (CAS: 71-43-2) yog dab tsi?
BenzeneCAS: 71-43-2 Nr., ib qho organic compound, yog qhov yooj yim tshaj plaws aromatic hydrocarbon. Nws cov tshuaj formula yog C6H6. Nyob rau hauv chav tsev kub.
Nws yog ib qho tsis muaj xim, pob tshab kua uas qab zib, combustible, thiab carcinogenic. Nws yog me ntsis soluble hauv dej, yooj yim soluble hauv cov kuab tshuaj organic, thiab tseem tuaj yeem siv los ua cov kuab tshuaj organic nws tus kheej. Benzene yog ib qho tseem ceeb raw khoom ntawm kev lag luam petrochemical.
Kev siv Benzene
Benzene feem ntau yog siv los ua ib qho nruab nrab los ua lwm yam tshuaj. Nws yog feem ntau siv rau hauv kev tsim cov nylon fibers, uas tau ua tiav rau hauv textiles thiab engineering plastics.
Cov me me ntawm benzene yog siv los ua qee hom roj hmab, roj hmab, cov xim, cov tshuaj ntxuav tes, thiab tshuaj tua kab.
